Usefulness of unwinding the colonoscope shaft loop via the universal cord for colorectal endoscopic resections.

The colonoscope shaft loop can be unwound by establishing a loop in the universal cord of the colonoscope to maintain the same endoscopic view during colorectal endoscopic resections.

Comparison of endoscopic ultrasound-guided drainage and percutaneous drainage combined with minocycline sclerotherapy for symptomatic hepatic cysts: A retrospective study.

Simple hepatic cysts (SHC) are generally asymptomatic and incidentally diagnosed using imaging studies. Asymptomatic SHC does not require treatment, but symptomatic SHC warrants treatment using different modalities, including intravenous antibiotic therapy, ultrasound-guided percutaneous catheter drainage (PCD) with sclerotherapy, and surgery. The dissemination of endoscopic ultrasonography (EUS) intervention techniques has enabled the performance of puncture and drainage via the transgastrointestinal route for intra-abdominal abscesses. Despite the development of an EUS-guided drainage method for treating symptomatic SHC, only a few case reports using this method have been reported. This study retrospectively analyzed the safety and feasibility of EUS-guided drainage of symptomatic SHC as well as its clinical outcomes and compared it with combined therapy using PCD and minocycline sclerotherapy. The records of 10 consecutive patients with 11 symptomatic SHCs treated with either EUS-guided drainage or PCD combined with minocycline sclerotherapy at the Musashino Tokushukai Hospital from August 2019 to January 2024 were retrospectively examined. All cases in both groups achieved technical and clinical success, with no reported adverse events. The median reduction rates of the major cyst diameters in the EUS-guided drainage and PCD with sclerotherapy groups were 100% (interquartile range [IQR]: 94%-100%) and 67% (IQR: 48.5%-85%). The length of hospital stay was 7 and 22.5 days in the EUS-guided and PCD with sclerotherapy groups (P = .01). EUS-guided drainage of symptomatic SHC is a safe and effective therapeutic alternative to percutaneous drainage with sclerotherapy and surgery for treating symptomatic SHC.

Splenic Abscess due to a Perforated Duodenal Ulcer Successfully Treated with Endoscopic Ultrasound-Guided Transgastric Drainage.

Splenic abscesses are rare, with a reported prevalence of 0.14-0.7% in autopsy studies. The treatment options for splenic abscesses include intravenous antimicrobial therapy, percutaneous drainage, and splenectomy. Although the dissemination of endoscopic ultrasound (EUS) intervention techniques has made it possible to perform puncture and drainage via the transgastrointestinal route for intra-abdominal abscesses where the percutaneous route has been difficult, there have been few reports of EUS-guided drainage of splenic abscesses. A case of a splenic abscess associated with a perforated duodenal ulcer that was successfully treated with EUS-guided transgastric drainage is described. An 89-year-old Asian woman with a perforated duodenal ulcer underwent surgery at another hospital. After surgery, the patient developed a splenic abscess, for which percutaneous treatment was anatomically difficult. Therefore, she was referred to our hospital for treatment of the splenic abscess using EUS-guided drainage. EUS-guided transgastric drainage was performed under sedation using a convex EUS scope. The splenic abscess, measuring approximately 4 × 3 cm2, was punctured using a 19-gauge aspiration needle. A 6-Fr pigtail nasocystic drainage tube was placed in the abscess cavity. The procedure was completed without any complications. After EUS-guided drainage, the abscess cavity decreased in size over time, and the patient had a good clinical course and was subsequently discharged. EUS-guided drainage of splenic abscesses may be a safe and effective therapeutic alternative to percutaneous drainage and surgery; however, large-scale investigations are required to confirm the present findings.

Usefulness of "Nelaton Attachment" for endoscopic submucosal dissection of colorectal neoplasms.

Background and study aims Although colorectal endoscopic submucosal dissection (ESD) has enabled high en bloc resection rates regardless of tumor size, colorectal ESD is still a challenging procedure. We developed a novel device called the Nelaton Attachment, which allows endoscopists to manipulate the ESD knives using two fingers of their left hand while holding the endoscope with their right hand. We retrospectively investigated the efficacy and safety of the Nelaton Attachment for colorectal ESD. We compared efficacy and safety between Nelaton Attachment and non-Nelaton Attachment groups, and also conducted an ex vivo experiment to evaluate the effect of the Nelaton Attachment. Patients and methods We retrospectively reviewed 36 consecutive patients with 37 colorectal tumors who had undergone ESD at Kishiwada Tokushukai Hospital and Naritatomisato Tokushukai Hospital between April 2016 and September 2018. The Nelaton Attachment was used for 22 of the 37 colorectal ESDs. In the ex vivo experiment, endoscopists inserted and withdrew an ESD knife 2 cm using two fingers of their left hand with and without the Nelaton Attachment. Results Median procedure time was significantly shorter in the Nelaton Attachment group (38 min [range 6 - 195 min]) compared to the non-Nelaton Attachment group (75 min [range 17 - 198 min]; P  = 0.030). Median time to complete the ex vivo experiment five times was significantly faster with the Nelaton Attachment than without the Nelaton Attachment ( P  = 0.001). Conclusions Use of the Nelaton Attachment for colorectal ESD is feasible and safe, and may facilitate colorectal ESD procedures.
